چکیده
We consider the periodic standing waves in derivative nonlinear Schrodinger (DNLS) equation arising plasma physics. By using a newly developed algebraic method with two eigenvalues, we classify all terms of eight eigenvalues Kaup-Newell spectral problem located at end points bands outside real line. The analytical work is complemented numerical approximation bands, this enables us to fully characterize modulational instability DNLS equation.

Modulational instability and nonlocality management in coupled NLS system
Abstract. The modulational instability of two interacting waves in a nonlocal Kerrtype medium is considered analytically and numerically. For a generic choice of wave amplitudes, we give a complete description of stable/unstable regimes for zero groupvelocity mismatch. It is shown that nonlocality suppresses considerably the growth rate and bandwidth of instability. For nonzero group-velocity m...
متن کاملModulational instability in periodic quadratic nonlinear materials.
We investigate the modulational instability of plane waves in quadratic nonlinear materials with linear and nonlinear quasi-phase-matching gratings. Exact Floquet calculations, confirmed by numerical simulations, show that the periodicity can drastically alter the gain spectrum but never completely removes the instability. The low-frequency part of the gain spectrum is accurately predicted by a...
متن کاملModulational instability of electromagnetic waves in birefringent fibers with periodic and random dispersion.
Modulational instability (MI) of electromagnetic waves in a birefringent fiber with a periodic dispersion (two-step dispersion management scheme) is investigated. The properties of new sidebands are studied. The strong variation of dispersion leads to the decreasing of the main MI region and the suppression of additional resonance. In the random dispersion case the MI of all frequencies of modu...
متن کاملModulational instability of dust ion acoustic waves in astrophysical dusty plasmas with non thermal electrons
Propagation of dust ion acoustic waves in plasmas composed of nonthermal distributed electrons and stationary dust particles is investigated. Nonlinear Schrdinger equation is derived to describe small amplitude waves, using the reduction perturbation technique. Modulation instability of dust ion acoustic waves is analysed for this system. Parametric investigation indicates that growth rate of...
متن کاملInstability of Periodic Sign-changed Waves for Sine-gordon Equation
The present paper deals with results of orbital instability of periodic waves related to sine-Gordon equation. Our periodic solutions obtained in our study tend to a kink wave solutions in the infinite wavelength scenario. The approaches used here will be the classical Grillakis, Shatah and Strauss’ theory.
